Topics: • Extraction Line Components • Placement • Status • Stands • Cabling & Service Routes • Scheduling

Extraction Line Components: - Placement Naming: 1) First Correction Magnet (horizontal & vertical) “RD 540101_JH-TEMP”

Extraction Line Components: - Placement • Bellows (unshielded) • L. E. Profile Monitor #1 • Cross below • Reducer below • Small Ion Pump below • Bellows (unshielded) • BPM #1 • Spool • Solenoid • Corrector Magnet #1 • Bellows (unshielded) • Zero-length reducer • L. E. Profile Monitor #2 • Cross below • Reducer below • Small Ion Pump below • Zero-length reducer • Bellows (unshielded) • 20° Vacuum Chamber • 20° Dipole (19. 8°) Questions: 1) 1 st Stand – Wider for 12” Cable Tray? 2) L. E. PM #1 – in SHOPS? (ETA? ) 3) 1 st Corrector – Where is it? (ETA? ) 4) L. E. PM #2 – Needs Modified (ETA? )

Extraction Line Components: - Placement • Spool • Quad, (ERL, modified aperture) • Gave Valve (unshielded) • Spacer Flange • Bellows (unshielded) • Corrector Magnet #2 (plastic) • DCCT • Conical Transition (Reducer) • BPM #2 • Bellows (unshielded) • Tee (Unshielded) • • Small Ion Pump below Bellows (unshielded) Questions: 1) Modified Quad – to be mapped (ETA? ) 2) Valve – on-hand? 3) Plastic Corrector – where is it? 4) DCCT – Supports? 5) End Bellows/Transition – Designer to support end.

Extraction Line Components: - Placement • • • Transition Spool FCT Conical Reducer L. E. Profile Monitor #3 BPM #3 Tee • Small Ion Pump below • Bellows (unshielded) • Spool (custom nipple) • Over-Focus Quad • Shielded Ceramic Break • Dump Questions: 1) Transition - 1 piece or 2 piece? 2) L. E. PM #1 – in SHOPS (ETA? ) 3) Lead wall – Needs painting?

Stands: (5) • 1 st – PM#1 / BPM#1 / Solenoid / Corrector • 2 nd – PM#2 / Ion Pump #3 / Dipole • 3 rd – Quad / Valve / Corrector / DCCT / BPM#2 / Ion Pump #3 • 4 th – FCT / PM#3 / BPM#3 / Ion Pump #4 • 5 th – Quad / Dump

Cabling & Service Routes: • Dump – Water / Gas / Cabling: - Routed down vertical tray D. S. of dump then under shadow of RHIC cryostat or in cable tray under RHIC. • Dump – Hydrogen Venting: - Routed U. S. and through top of most upstream doghouse. • All components U. S. of Dump: - Drop from overhead near RHIC Extraction, then down under stand legs. • 4 th Stand components ? ? : - Route from vertical tray D. S. of dump then through tray under RHIC? (coming from D. S. will leave ~30” wide duck-under between 3 rd & 4 th stands. )

Schedule: • October: • 5 th Stand Assembly Completed: • • Dump connections – Water, Internal BLMs, Ground, Hydrogen Vent Vacuum – Ceramic Break, Spool through Quad, Leak check Quad – Survey Shielding Closed – Doghouses, Lead brick wall, Backstop, External BLMs • 1 st - 4 th Stands: • Build (919 B) • • • Finish Detail Drawings Build Rex. Roth Frames (919 B) Order / Install Aluminum Support Parts (central shops) • Install / Survey Stands in RHIC • Install Cable Tray through stands • Start Installing Extraction Line Components (1 st - 4 th Stands): • Magnets, Profile Monitors, BPMs, Vacuum Chambers / Pumps

Schedule: • November • • • Finish installing components Dress cables Close vacuum Install μ-metal Install bake-out blankets Start bake-out • December • Bake-out complete • Wire & test components • Install corrector
